This was actually discussed a while back (a month or two ago). It got really bogged down when someone pointed out that they were running CPUs with different clock rates in their SMP box, just to see what the net effect would be. THe problem was, of course, which one do you report, when the numbers don't match exactly, and/or how do you report both (or N)? -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
